This invention relates to a method and device for storing and retrieving media disk.
A jewel case is commonly used for packaging and containing disk media such as compact disks (“CD's”) and digital video disks (“DVD's”). The jewel case is typically made of plastic, with two opposing transparent halves hinged together to form the casing. The front lid and the back half can pivot to open and close the casing. A media tray is mounted on the back half gripping the disk by its central aperture.
In this conventional design of the disk case, when a user intends to retrieve the disk from the case, he or she has to pivot the front lid away from the back half, which requires sufficient space for the front lid's pivoting. This need for additional space when opening and closing the case creates considerable inconvenience, especially where multiple disk cases are disposed side by side. The user needs to take out a selected disk case from the stack of cases before he or she can open the case. U.S. Pat. No. 6,237,763 (“the '763 Patent”), issued to Kwok Din Lau on May 29, 2001, represents one of many examples that describe the conventional design of the disk case.
Another problem posed for use of jewel disk cases is how to arrange and organize a large number of them. The conventional approaches, such as placing them in a specially customized rack or a regular shelf, fail to provide an orderly, flexible, yet cost-effective method to arrange disk cases.
Given the above deficiencies of prior art, there is a need for a case that stores and contains a media disk, such as CD's and DVD's, Blu-ray disks (“BD”), micro chips and/or any other forms of storage devices. According to the present invention, the disk is received by a tray that is disposed within the case and such tray is slidable in relation to the base of the case. The innovative case includes a structure that enables stacking a plurality of the cases side by side in horizontal and vertical arrays to arrange them in a flexible and organized manner.
The media disk case in accordance with the present invention includes a base, a cover pivotally connected with the base and movable between an open configuration and a closed configuration; and a tray disposed on the base for receiving the media disk. The tray is slidable above the base between a position internal to the case, in a locked position and a position external to the case, in a released position. When the tray is forced inward from the locked position, it will be pushed out to the external, released position.
Advantageously, the innovative case includes a resilient bar mounted on the base. The resilient bar exerts bias against the tray when forced inward from the locked position. The case preferably has a hook for engaging the tray when the tray is forced inward from the released position.
Preferrably, the tray has an island mounted thereon for the hook to engage therewith. The island forms a path for guiding the hook to a position to release the island when the tray is forced inward from the locked position. Optionally, the hook is made of a resilient material such that the hook is biased to return to an original state. The case further includes two rails mounted on the base, the two rails being spaced from each other and each forming a track for the tray to slide through.
In one aspect of the invention, the slidable tray has a protruded portion for engaging the media disk. The protruded portion may consist of a plurality of resilient tabs. The tabs are biased against the circumference of the central aperture of the disk to engage the disk such that when the tabs are depressed, the disk is out of engagement by the tabs.
According to another aspect of the present invention, the media disk case comprises a base, a cover pivotally connected with the base and movable between an open configuration and a closed configuration, a tray disposed on the base for receiving the media disk; and a fastener for attaching the case to one another in horizontal or vertical directions. The cover and the base each have a groove that matches each other when in the closed configuration, and the grooves are adapted to receive the fastener. The groove is advantageously of cove shape, and the fastener is made of a resilient material that can snap in the cove-shaped groove.
Preferrably, the fastener includes two expanded portions in its two ends. The fastener can be detachably connected to the base.
Other than the base 120 and the slidable tray 110, the disk case 100 encompasses a cover 140 pivotally connected with the base 120 through a hinge portion 150 and rotatable between an open configuration (as shown in
The disk tray 110 is disposed over the base 120, having two walls 320a, 320b (shown in
Referring to
Over the base 120 of the disk case 100 are also mounted two hooks 410a, 410b. The hooks 410a, 410b work with corresponding islands 310a, 310b mounted on the back of the tray 110 to lock and release it.
Referring to
From the external, released position, the disk tray 110 can be pushed inward back to an internal, locked position, as shown in
Referring to
In some embodiments, the case 100 has bores 732a-732d formed in its front side 725 and back side 727, near the top end 715 and bottom end 717 of the case 100. A horizontal fastener 730, preferably in a long, narrow, and thin shape, is configured to fit its two expanded end portions 734a-734b into the bores 732a-732d, so as to attach the cases 100 horizontally in a stable manner. The horizontal fastener 730 is advantageously made of resilient materials such as plastic.
In some embodiments, the horizontal fasteners 730 are detachably connected to the base 120, as illustrated in
Having now described the invention in accordance with the requirements of the patent statutes, those skilled in this art will understand how to make changes and modifications in the present invention to meet their specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention as set forth in the following claims.
